The Commercial Building Disclosure (CBD) Program is a regulatory program administered by the Department of Industry, Science, Energy and Resources (DISER) that requires energy efficiency  information to be provided in most cases when commercial office space of 1000 square metres or more is offered for sale or lease.

Due to the impact of COVID-19 on travel restrictions and social distancing, the Department has released updated Tenancy Lighting Assessment (TLA) Rules and an associated TLA Ruling to provide flexibility for building owners to meet their obligations under the CBD Program, while allowing building assessors to safely complete their work remotely where needed. The following resources are to assist those potentially affected by current COVID-19 preventive measures:

Updated TLA Rules

TLA COVID-19 Ruling v.20

COVID-19 Guidance Notes
